MQX + fsl_adc16 + Processor Expert

I am using fsl_adc16 component from PE for my mk64F micro on KDS V3 IDE with MQX RTOS(V4.2). My ADC configuration files(generated by PE) for the project are attached for your reference. For the ADC16_DRV_GetConvValueRAW() what is channel group ID? what is the usage for the functions for fsl_adc16? Is there any reference manual for the functions of PE components? Is there any example project reference for these components?
